Abstract
The utility model discloses a cylinder block forging mould which comprises an upper mould base, a lower mould base, a forming cavity and an rough-edge groove, wherein the forming cavity is formed between the upper mould base and the lower mould base, and the rouge-edge groove is arranged on the joint position of the upper mould base and the lower mould base and is communicated with the forming cavity. The rough-edge groove comprises a rough-edge groove body, an arc-shaped groove bridge part and a straight groove bridge part, wherein the arc-shaped groove bridge part is communicated with the rough-edge groove body, and the straight groove bridge part is communicated with the arc-shaped groove bridge part. The straight groove bridge part is communicated with the forming cavity. Due to the fact that the rough-edge groove is designed into the rough-edge groove body, the arc-shaped groove bridge part and the straight groove bridge part, the arc-shaped groove bridge part is communicated with the rough-edge groove body, and the straight groove bridge part is communicated with the arc-shaped groove bridge part, the phenomenon of tearing around the rough edge of a forged piece is reduced in the trimming process, the forged piece is not prone to deformation, and the product quality is guaranteed.
Description
Technical field
The utility model relates to a kind of cylinder body forging die.
Background technology
At present, the cylinder body forging die, generally include upper bolster, die shoe, be formed at forming cavity between described upper bolster and described die shoe, be arranged at described upper bolster and the junction of described die shoe and the burr groove that is connected with described forming cavity, general burr groove comprises burr groove body, is communicated with the straight trough bridge section between burr groove body and forming cavity, yet in the trimming process, phenomenon can occur tearing around the burr of forging, even make forging produce distortion, affect forging quality.
The utility model content
The purpose of this utility model is to overcome the defective that exists in prior art, and a kind of cylinder body forging die is provided, and guarantees that follow-up die forging is produced normally to carry out, and guarantees forging quality.
For achieving the above object, the technical solution of the utility model has been to provide a kind of cylinder body forging die, comprise upper bolster, die shoe, be formed at forming cavity between described upper bolster and described die shoe, be arranged at described upper bolster and the junction of described die shoe and the burr groove that is connected with described forming cavity, described burr groove comprises burr groove body, the deep-slotted chip breaker bridge section that is connected with described burr groove body, the straight trough bridge section that is connected with described deep-slotted chip breaker bridge section, and described straight trough bridge section is connected with described forming cavity.
As preferably, the length dimension of described straight trough bridge section is greater than its width dimensions.
As preferably, be provided with detent mechanism between described upper bolster and described die shoe.
As preferably, described detent mechanism comprises the locating dowel that is fixedly installed on described die shoe, is opened in the locating slot on described upper bolster, and described locating dowel matches with described locating slot.
As preferably, be provided with bevelled edge on described upper bolster, be provided with relatively symmetrically lower bevelled edge on described die shoe.
As preferably, the below of described forming cavity is fixedly installed push rod.
Advantage of the present utility model and beneficial effect are: by the straight trough bridge section that the burr groove is arranged to burr groove body, the deep-slotted chip breaker bridge section that is connected with described burr groove body and is connected with described deep-slotted chip breaker bridge section, in the process of trimming, around reducing the forging burr, phenomenon appears tearing, make forging not yielding, guarantee product quality.
